Started with http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=179284
which doesn't seem to be related, so looks like a latent sel-sched bug.
The note the assert fails on is NOTE_INSN_DELETED, so one has to wonder why we
don't throw such notes away during the scheduling, or at least don't fail the
assertion on those.
